Lang Chip Fan - Anyone Use One?

Referring to these guys:

I'm considering one to avoid having to blow my parts off with a blow gun. I thought about turning on air blast and cycling the table left and right at the end of a program...I don't think it'll be too effective.

Anyway, anyone ever use one? Differences between larger and smaller model? Any one size better than the other. Does it really get all(most) of the chips away?

Thanks

I went to the local hobby store and spent a total of about $4 for a airplane propeller. Mounted it on a 1/4" bolt in a tool holder. Orient the blades so that they are 90degrees to you tool changer carasel/umbrella/tool chain.

Works Excellent! Spin it up to 8,000 RPM in M4 and blow off about 2" off the part.
Really cleans things up.

Take the $400 you saved, and have a nice dinner, with your friends. More than once.

Yes, they work very, very well. We use them in a low volume production environment.

This man is a genius!

I want a prop that I can mount on the shank of a boring head to do the clean up during the dry boring pass.

Prop trick sounds neat. I think I'm limited on tool diameter. What diameter prop did you use?

Tony,
What size chip fan? I'm leaning toward the large one.

Tony, I have been looking at purchasing one of these fans. How well do you think they would work for blowing coolant out of large pockets? Say 10" x 10" x 3" deep.

 

[StreetSpeed]

I want one too. I was hoping someone would make a knock off however, because as someone insinuated above, $250 for that thing seems a bit steep for what it is.

A pneumatic powered vacumm mounted to you head powered with m code fired valve would be a better option for draining a pond of that magnitude.

Something like an Exair Line vac.

for ponds....dont someone make a blowgun with a drop on it for siphoning? might be too messy...but so is blowing out a pond.

Our parts have about 1/2-1" of coolant in several pockets, some of them quite small openings, but it gets them empty. For a pocket that big with a lake in it, you'll have to play with distance and rpm to keep from making a big mess. Our main reason for them is to get the chips off the fixture, the machines are robot loaded and we don't want lingering chips.

Not sure which model, it's about 8" or so expanded.

Thanks Tony

Worst part is that is only one pocket on these plates. The plates are 100" x 40" & have 14 of these pockets. We are using sump pums with mixed results.
I think these fans are worth trying. We will see.

OK guys I'm in the minority (what's new) but seeing as you CNC merchants worship the great god speed, I'd like to know how another toolchange, spindle ramp up, table shunt about, ramp down, tool change, stacks up against an air blast?

The tool diameter limitation is NOT a limitation. Just mount the prop so it sits in the tool changer "sideways" at 90 degrees to the tools next to it.
A 6" or 8" should be No Problem in most any machine. I've ran it in the Robodrill, and the Cincinnati's.
You don't need the super expensive Folding props. Just mount it in the tool changer so that it goes between the adjacent tools in the tool changer.

Do you want to be the guy blowing 20-30 gallons of coolant out of a mold pocket?

Of course not, but if you can program air blast cooling or liquid cooling I'm sure you can program a coolant & chip clearing blast.

There are a lot of machines that don't have air blast. I'm going to hobby shop this weekend and give the prop deal a try.

Well for one thing it saves you compressed air from the operator spending 10 mins blasting crap everywhere, and it saves the doofus operator having to goto hospital to have a piece of metal removed from his eye like yesterday.

I like them, cant remember the brand but the ER32 holder plus fan did'nt come to more than £35 each
